I/O System

Rack-based I/O

The rack-based I/O system consists of a central rack and one or two 19 inch expansion racks intended for double size Euro boards. Each rack is equipped with a power supply unit PSF.

For a SattCon 35 system the control unit CU45 is connected to the central rack.

For a Series 200 system connected to a central rack-based I/O, a rack adapter board 200-RANN is mounted in the central rack. This board communicates with the Series 200 CPU via the system bus.

For a Series 200 system connected to a remote rack-based I/O, a rack adapter board 200-RACN is mounted in the central rack. This board communicates with the Series 200 via the ControlNet™ network.

Two expansion racks can be connected to the central rack in a central I/O system and one in a remote I/O system. Each expansion rack is equipped with a bus decoder board PBAD, which communicates with CU45, 200-RANN or 200-RACN in the central rack through a parallel bus cable.

The rack-based system is intended for industrial use and meets the EMC directive 89/336/EEC and the Low Voltage Directive, LVD, 73/23/EEG.

The rack-based I/O has the following main features:

High density I/O system Replacement with power on Large number of I/O boards and

accessories Central or Remote I/O Compatible with both SattCon 35

and Series 200 Digital and analogue I/O boards are

galvanically separated Easy connection of shielded cables Simple upgrading of older I/O

ODPG.8Digital output board for DC voltage with 32 optocoupled outputs, divided into four separate groups of eight. Themaximum output capacity is 0.8 A per output, subject to maximum 3.2 A per group and 8 A for the entire board.

ODPG.8 is designed for supply voltages between 10–60 V. Since the four groups are completely separated from each other, it is possible to use foudifferent supply voltages for the same board.

Several outputs can be connected tothe same load if they are fed from the same voltage source. If not, they need thave a protective diode in series with the output.

ORG24Digital output board with 16 relay outputs. The relays have single-pole change-over contacts and are providedwith varistor protection.

Maximum relay contact current is 2 Aand maximum relay contact voltage is 250 VAC alternatively 120 V DC.

The supply voltage to the relay coils (24 V DC) is connected to a terminal located on the rear side of the rack.

ODSGDigital short-circuit proof output board with two groups of 16 optocoupled outputs powered by an external supply(+19–30 V DC). Each group is monitored by an overload/short circuit detection bistable. The maximum loadis 0.8 A for each output and 16 A for thecomplete board.

ODSG is intended for loads such as lamps, relays, solenoid valves etc.

IPA4IPA4 is a digital input board designed to count pulses. The maximum pulse frequency is 10 kHz.

IPA4 has four inputs, each with an 8-bit counter, capable of counting up to 255 pulses. The inputs can be combined in pairs to make two 16-bit counters with a capacity of up to 65535 pulses.

To suppress electrical interference, transmitters with complementary signals should be used.

Phase displaced pulse trains can be used for up/down-counting. The counters can be started, stopped and reset individually.

The common signal reference voltage level can be adjusted and detection of positive and/or negative-going edges can be selected individually for each input.

IPA4 can be used in applications for pulse counting, quantity counting, positioning and speed calculation.

16 LEDs on the front panel show the four counter channels, each with two inputs A and B. The inputs A and B can be combined in different ways, to measure motion in two directions, for instance.

Three sockets for test purposes are located on the front.

The counter channels also have gate inputs to start and stop the counting, and clear inputs to reset the respective counter.

All the input circuits are provided with comparators for transmitters with complementary signals, a means to effectively suppress electrical noise.

IBAAnalogue input board with eight inputs. IBA can either be used on its own or with associated modules. The plug-in modules are for galvanic isolation (MCVG), differential input (MCV200), temperature measurement (MP, MN) or resistance measurement (MR).

When IBA is used without associated modules, the following inputs can be connected: 0–20 mA, 4–20 mA, 0–10 V0–5 V and 1–5 V. Each channel is individually selectable by straps, located on the board.

IBA has high flexibility, very high repeatability and high temperature stability.

If the LED input (current) is used, theintensity of the LED varies with the value of the input signal.

OCAHGAnalogue output board with four channels for voltage signals 0–10 V ancurrent signals 0–20 or 4–20 mA, selectable with straps on the board. Thresolution is 8 bits.

The analogue circuits are electricallyisolated from the digital control logic and the control system. The channels are not galvanically separated from eacother.

OCAHG generates analogue signalsto control devices, instruments, etc. Bymeans of the signals DDC and MAN, control can either be automatic (from the control system) or manual via the INCREASE/DECREASE inputs.

Manual control can be executed froma hand module, push-buttons or a digitaoutput board.

OCAHG retains its output values in the event of a CPU failure.

OCVAAnalogue output board with two channels for current signals 0–20 mA o4–20 mA and voltage signals ±10 V or0–10 V. The various ranges are selecteusing connections in the process connector cable.

Each channel can supply both currenand voltage output signals at the sametime. When using a current output the corresponding voltage range must be sto 0–10 V.

The analogue circuits are electricallyisolated from the digital control logic and the control system. The channels are not galvanically separated from eacother.

OCVA can be set up so that the outputs either go to zero or remain at thselected safety state values during CPshut down.

The board has 12-bit resolution for the ±10 V ranges and 11-bit resolutionfor the other current and voltage range

ConfigurationThe central and the expansion racks are of a common type called PIOS35. The rack has space for 16 I/O boards and all input/output boards fit in any slot intended for I/O boards.

The I/O boards are connected to the rack via two different connectors. The lower connector (X2) is used for connecting the rack’s internal bus and power supply. The upper connector (X1) is used for connection of input/output signals for the process using crimp sleeves.

For more detailed information, see the manual ”Rack-based I/O, Installation and Maintenance”.

Bus systemThe signals between the racks are distributed via parallel bus cables. Two expansion racks can be connected to the parallel bus. If RACN or RACN/A is used, only one expansion rack may be connected.

There are two lengths of the cables to be used between the central rack and the expansion rack, or between the expansion racks. Their lengths are 1 and 2.5 metres, although only one 2.5 metres cable may be connected in a system.

Mains supply Each rack contains a power supply PSF, located at the right hand side of the rack. It can be supplied via the mains or 24 V DC. Filters and mains connections are fitted at rear of the rack.
